Wasn't there a guy who sold drugs to a friend or relative of Uncle Junior's tailor,and after the kid overdosed,Junior had Mikey Palmice kill the dealer on a bridge.Junior took a big risk for no good reason. It's not as if the guy did anything to the Soprano Family or Junior personally. Potentially,if Junior was linked to the hit,he would have gone away forever.

It kind of reminds me of the totally ridiculous hit on Arnold Shuster that cost Albert Anastasia his Boss spot,and ultimately his life.
